Specification of Letters Patent.

Patented June 25, 1907.

Application filed November 30, 1906. Serial No. 345,690.y

To all whom it may concern:

Be it known that we, GEORGE B. YOUNG and JOSEPH H. YOUNG, both citizensof the United States, andresidents of El Paso, .in the county of El Pasoand State of Texas, have invented a new and improved Corn- Popper, ofwhich the following is a full, clear, and exact description.

This invention is an improved device, especi'ally designed for poppingcorn, although not limited to this particular use as it may be usedadvantageously in roasting peanuts and chestnuts and as a cooking devicegenerally.

The object of the invention, primarily, is to provide for the cooking,roasting, etc. prefer` ably by electrical. means in a manner that thesame may be carried out uniformly and also provide for the automaticrelease of the cor from the .popper should the pan in which it iscontained ll to ,the overflowing point.

Reference is to behad tothe accompanying drawings forming a part of thisspecification, in which similar characters of reference indicatecorresponding parts in all the figures. l

Figure 1 is a side` elevation of one embodiment of our invention; Fig. 2is a fragmentary view similar to Fig. 1, yshowing the pan and lidseparated; Fig. 3 is a central, vertical section through the lid andpan, showing in dotted outline the position assumedby sectors of the lidas when the pan fills with corn to the overflowing oint, and Fig. 4 is ahorizontal section su stantially on the line 4 4 of Fig. 3, looking inthe direction of the arrow.

In carrying out the invention we employ a support 1, preferably in thenature of a box, in which is contained a motor intergeared with avertical driving'shaft y2, as shown in dotted outline in Fig. 1. Thisshaft 2, which distance above the top thereof, where it is provided witha transverse pin 3, adapted to engage in the slots 4 of a thimble 5, asshown in Fig. 3, holding said thimble yagainst yrelative rotary movementon the shaft. The upper end of the thimble 5 is threaded into acenter-plate 6, which is secured to l.the under wface of a sheet metalcup 7, a sheet of material 8 being interposed between the plate and cupto insulate them from eachother. Seated or telescoped within the cup 7is a pan 9 o f similar construction and forming with the cup a heatingchamber therebetween for containing a suitable heating devicehereinafter referred to. The pan and cup are both pref- 3 erablyconstructed of aluminium and are rigidly secured together by screws orbolts 10 which also pass through brackets 11 arranged about the cup thelatter, supporting a wire, 11a encircling the pan and forming a handleadapting both the cup and pan to be lifted from the end of the shaft 2for emptying the pan or other purpose.

Fixed to the support 1 at one side of the shaft 2, is a standard 12, tothe upper end of which is pivotally connected a hand-lever 13, normallyforced in the direction of the pan by a spring 14 connecting the leverwith the standard 12. The end of the lever 13 overhang-ing the an 9 isdownwardly-turned and has rigidly ed thereto at its extremity anagitating device consisting of transverse arms 13a and also fixedthereabove a lid 15, which is preferably shaped as the frustum of acone, with hingedly connected sectors 16, said sectors adapted to moveoutwardly to the dotted position shown in Fig. 3 should the pan becomefilled with popped corn to the overflowing point, For holding the lid 15in an elevated position in .order that access to the pan may beobtained, is provided a'projection or pin17 extending fromfthe lever 13at the opposite side of its pivotal connection, said pin being adaptedto be engagedbyfa spring hook 18- carried by the standard 12, main#taining the lever and lid as illustrated in Fiof. 2.

The compartment or chamber between the cup 7 and pan 9 is lined with aisheet insulating material 19 and 20, respectively,` said material beingpreferably mica, as also a disk 21 arranged at the center of saidchamber. This disk, as also the parts 6 and 8, are pierced by insulatingnipples 22, -through which pass `conductors 23 and 24 leading to theterminal points of a heating coil ,25 arranged in the compartmentbetween the cup and pan. This coil, as shown in Fig. '4, which ispreferably of German silver, is 1n the nature of a wire deeply corrgatedand bent into the form of a ring. The conductors 23 and 24, as shown inFig. 3, lead from contact rings 26 and 27, respectively, surrounding acylinder 28 of wood or other insulating lmaterial, said cylinder beingrigidly fixed to the thimble 5. The rings 26 and 27, when the pan isseated over the shaft 2, are engaged by brushes 28 and 29, respectively,the latter being coupled by suitable conductors to any source ofelectrical supply, through bindingposts 30 and 31.

It isA obvious from the constructiondescribed vthat when the shaft 2 iscaused to revolve, thepan and attached mechanism when engaged therewith,will be likewise driven. During this operation the coil 25 isheated froma suitable source of electrical supply, causing the cooking or roastingto take place uniformly throughout, through-theaction of the stirring oragitating device 13u. If the material in the pan be popcorn, the corn,after popping, lwill remain in the pan until the same is filled to theoverflowing point, after which it will raise the sectors 16 and permitthe corn to fall from the pan.

Although we have described the preferred embodiment of the invention indetail, in or- `der that the construction and operation might be fullyunderstood, we. regard the precise construction as not material and thatthe scope of the invention is limited by the scope of the annexedclaims.

Having thus described our invention we claim as new and desire to secureby Letters Patent:
